…MConnection When running over the wmi protocol the module now reuses the protocol's authenticated IWbemLevel1Login instead of creating its own DCOMConnection to the same target - whose disconnect would clash with the protocol's own on impacket versions that do not guard the INTERFACE.CONNECTIONS thread entry (KeyError: ThreadPoolExecutor-x_x). Over smb nothing changes: the module still creates its own DCOMConnection since the protocol has none.
…nd DCOMConnection Same pattern as the rdp module fix: BitLockerWMI creates its own DCOMConnection to the same target the wmi protocol already holds one for, and disconnecting it removes the shared INTERFACE.CONNECTIONS thread entry, so the protocol-level disconnect afterwards raises KeyError on impacket versions that do not guard it. Reuse the protocol's IWbemLevel1Login instead - over smb nothing changes.
Enumerating the shell resource succeeds for any WinRM-authorized user, so every valid login was reported as (Pwn3d!). admin_privs now comes from a WinRM configuration read - admin only, milliseconds on both paths. Command execution is probed separately by opening each shell endpoint (cmd and PowerShell runspace have separate SDDLs) without running a command, shown SSH-style: [+] dom\admin:pass (Pwn3d!) Shell access! (all) [+] dom\user:pass Shell access! (cmd only)
…lter The query is sent as a wsman:Filter with the Microsoft WQL dialect and executed server-side (projection and WHERE included) - no PowerShell process on the target and no DCOM access. Results are pulled until EndOfSequence. Gated by requires_admin: the WinRM service WMI plugin only serves Administrators, Interactive and Remote Management Users (network logons lack the Interactive group), and the namespace itself needs Remote Enable on top.
…nections, bitlocker wmi_invoke on the winrm protocol executes a WMI method natively over WS-Management (method INPUT body in the class resource URI namespace, instance addressed by a selector on the class key property) - no PowerShell process, the WinRM equivalent of the smb/wmi protocols calling WMI methods over DCOM. Four modules gain winrm support on top of the wmi_query and wmi_invoke primitives: rdp (enable/disable, RAM, port), enum_dns, get_netconnections and bitlocker, with the fault code mapping in faults.py.

Description
Adds
wmi_invoke()to the winrm protocol: native WSMan ExecMethod for WMI method calls without PowerShell or DCOM. Parameter names match the class schema (not always MSDN, e.g.Win32_TerminalServiceSetting.SetAllowTSConnectionstakesAllowTSConnections), and the target instance is addressed by a selector on the class key property.Four modules gain winrm support:
